Thanks for all of the suggestions. I think at some point I’m going to try them all for myself. I’ve decided life is too short to drink mediocre coffee.
For now, for my son-in-law, I went with La Colombe. I noticed there is a cafe in their city, so I asked my daughter if they’ve ever heard of it. It turns out they
have been there. They only have had canned (!) iced coffee from there, but she said it was very good. I figure this way, if he really likes one of the ones I sent him, he can just go there and stock up easily.
Thanks again!
